It didn't take long for A.J. Brown to figure that out. The Titans rookie wide receiver, only a couple of weeks into his new gig, already has started plucking Davis’ brain for every usable tidbit. Davis, after all, was in Brown’s shoes only two years ago, when he was the fifth overall pick in the 2017 NFL Draft.

“You just try to learn as much as possible from that guy,” said Brown, the team's second-round pick – 51st overall – in this year's draft.

It was evident Tuesday, when the Titans held their second practice of the spring and the two were seen chatting often after reps. Then, after the rest of the team headed to the locker room after practice, Brown hung back with Davis, getting in some extra one-on-one reps. The two spent a few minutes working together.

“You’ve got to pay the cost to be the boss. So I’m out here with Corey – that’s the guy,” Brown said. “Like I said, me learning everything I can, me getting these extra reps after practice are going to roll onto the field when we practice.”

What are some of the things the 6-foot-3, 209-pound Davis is working on with the 6-foot, 226-pound Brown?

“Releases. Just working my hands a lot," Brown said. "We’re bigger receivers, so a lot of guys probably try to jam us that are smaller. Just being stronger (than them)."

Davis, meanwhile, is still chipping away at his own game. He had 65 catches for 891 yards and four touchdowns during his second season in 2018. Those extra reps after practice are geared toward improving himself, too.

"They're huge," Davis said. "I mean some of the time we don’t get all the reps that we want at practice. So we’ve got to come out here and just put in the extra work, catch extra balls, extra releases, whatever it may be, to kind of take our game to the next level, and that’s what we’re going to do."

Davis thinks that extra work can go a long way in helping Brown transition from an ultra-productive collegiate player to an NFL success.

"He’s a great player," Davis said. "The best thing is that he’s able to come out here and work. His work ethic is crazy, and I’m excited to see what he’s going to do for us."
